Starry Night - by Abo Formation

A natural version of Starry Night seen on a boulder of Abo Formation in Carrizo Arroyo. Reduction spots form where small bits of organic matter consume oxygen during diagenisis and consequently change the oxidation state of iron.

Carrizo Arroyo is on NM State Land in the Lucero uplift west of Los Lunas, NM.  Road access is difficult through private land.
